This introduces a callback to relaunch a service rendezvous circuit when a previous one failed to build or expired. It unifies the legacy function rend_service_relaunch_rendezvous() with one for specific to prop224. There is now only one entry point for that which is hs_circ_retry_service_rendezvous_point() supporting both legacy and prop224 circuits. Signed-off-by: David Goulet <dgoulet@torproject.org>
